On some South-African Phyllopoda. 27 



yellowish or reddish tinge, caudal segments in fully grown 

 specimens generally banded ventrally with orange, marsupium 

 of female richly coloured with orange, crimson and blue? 

 caudal rami in male tinged with light orange. Length of fully 

 grown female 12 mm., of male about the same. 



Remarks. — The present form cannot properly be re- 

 ferred to any of the hitherto established genera and sub- 

 genera of Branchipodids, and I have therefore felt justified 

 in establishing for its reception a new genus, which is named 

 as above on account of a certain resemblance to the genus 

 Brcmchi'pus (sens, strict.). The total absence of any frontal 

 appendages in the male is a character which this genus 

 shares with the genus Brandunecta : but in the latter the 

 marsupium of the female is prolonged to a narrow pouch 

 as in Streptocephalus, and the caudal rami are very different. 

 Moreover the ovaria are not, as in JBranchimcta, contained 

 within the trunk, but are confined to the tail and genital 

 region, as in most other Branchipodids. At first I was 

 inclined to regard the present form as identical with the 

 JBranchipus abiadi of Brauer; but on a closer comparison 

 I find that it differs in so many essential points, that it 

 must evidently be regarded as specifically distinct, though 

 Brauer' s species ought undoubtedly to be included in the 

 same genus. I have much pleasure in dedicating this 

 interesting form to the distinguished zoologist Mr. J. V. 

 Hodgson, to whom I am indebted for the material from 

 which this, and the 3 other Phyllopoda here described were 

 reared. 



Description. — The length of fully grown female speci- 

 mens, measured from the front to the end of the caudal 

 rami, does not exceed 12 mm., and male specimens are 

 scarcely larger.
